Abstract: PROBLEM TO BE SOLVED: To enable clearing of resolution limits in screen printing by laminating a first electrode layer of an electricity-machine conversion element which changes the volume of a liquid chamber and an electricity-machine conversion material layer on the first electrode layer and a second electrode on the electricity-machine conversion material layer in such a manner that the second electrode is connected to and laminated on the electricity-machine conversion material layer through a contact hole in an interlayer insulating layer. SOLUTION: An electricity-machine conversion layer 4 is formed on the upper layer of an Si substrate 1 through an intermediate layer 2 and a lower electrode 3 is provided in the conversion layer 4, and further, the intermediate layer 2 prevents a chemical reaction from taking place between the Si substrate 1 and the electricity- machine conversion material 4 containing lead. An electricity-machine conversion material 4 is sandwiched between an upper and a lower electrode and becomes distorted by applying an electric field between the electrodes. Further, a contact hole 6 for bringing an upper electrode 7 into contact with an interlayer insulating coat 5 and the electricity-machine conversion material 4, is formed.  Next, a blocking plate with a hole for conveying a liquid, a plate with a granule resistance, a nozzle communicating hole and a common liquid chamber arranged, and a nozzle plate are joined sequentially to the back face of the Si substrate 1 to construct the ink jet head.

Inventor: PIITAA JIEI ENSHIYU
IPC: B65G45/08
Filed: 1997-01-29
Abstract: PROBLEM TO BE SOLVED: To eliminate a discrete mechanism for lubricating a conveyer chain by its curved part, by providing a lubricating insert by which fluid lubricant is discharged from a porous material, and which forms a lubricating film between a guide surface and a thrust surface. SOLUTION: A thrust surface 64 which is brought in contact with and supported on the guide surface of an inside wear strip 28, is formed on the outside surface 60 of an inside rib 56. Frictional force is generated between the guide surface of the inside wear strip 28 and a thrust surface 64 by moving a chain. These frictional force generates heat so as to heat a lubricating insert 72. A small amount of fluid lubricant 82 is discharged from the dead space of a porous material 80 by capillary action according to heating. The discharged fluid lubricant 82 forms a thin lubricating film between the guide surface of the inside wear strip 28 and the thrust surface 64 of a link.  A lubricating effect is continued until the lubricating film is eliminated, and when eliminated, frictional force heats the lubricating insert 72 again, and the small amount of the fluid lubricant 82 is further discharged.

Abstract: PURPOSE:To improve the recognition accuracy and the maximum likelihood of a partition point by using two kinds of neural networks, and executing the recognition of a partition by taking notice of an electrocardiogram waveform of that time and a timewise structure of the partition. CONSTITUTION:At the time of recognizing a partition at the time point (t), a value of an electrocardiogram waveform to be recognized and a prediction Ft of the partition of the time point (t) of a partition buffer 14 are inputted to a pattern associative type neural network 12. Consequently, a recognition result Kt of the partition of the time point (t) is obtained as the output of the pattern associative type neural network 12. This recognition result Kt becomes the input of a recurrent neural network 13. Thus, the prediction Ft+1 of the partition of a time point (t+1) is obtained as the output of the recurrent neural network 13. This prediction Ft+1 is stored in the partition buffer 14, and used for recognizing the partition at the time point (t+1). The partition buffer for holding the prediction of the partition of the next time point is initialized prior to the recognition.
